Rhombus
Definition, properties, and formulas for rhombus calculations
Overview
A rhombus is a quadrilateral with four sides of equal length. Opposite sides are parallel, opposite angles are equal, and the diagonals intersect at right angles.
Key properties:
- Opposite sides are parallel
- Opposite angles are equal, adjacent angles sum to 180°
- Diagonals bisect each other and are perpendicular
- Each diagonal bisects a pair of interior angles
- The diagonal intersection is the center of symmetry
It has an incircle and is therefore a tangent quadrilateral.
